ExecuJet MRO Services Australia has achieved a milestone in Australian aviation maintenance, completing the country’s first-ever 120-month heavy maintenance inspection on an Embraer Legacy 500. This landmark achievement took place at ExecuJet’s state-of-the-art facility located at Essendon Fields Airport in Melbourne. Not only does this solidify the company’s position as a leader in advanced MRO capabilities, but it also reinforces Australia’s growing role in supporting high-end, complex business jet maintenance within the Asia-Pacific region.
Delivered new in 2015, the Embraer Legacy 500 in question was the first of its model to enter service in Australia. The jet returned to its birthplace of maintenance for this demanding inspection, staying with the same MRO provider that has maintained it since delivery. This continuity, paired with a decade of operational data, provided a rich backdrop for this extensive overhaul.
Deep Dive Into the 120-Month Inspection Procedure
The 120-month inspection is one of the most exhaustive scheduled maintenance checks in an aircraft’s lifecycle. Designed to ensure airframe integrity, mechanical performance, and operational safety, the inspection involved extensive disassembly and systems testing. Technicians removed all cabin and cockpit furnishings, including sidewalls, carpets, and overhead panels, allowing unrestricted access to the fuselage’s primary structural elements. The aircraft’s flight control surfaces were detached to inspect their attachment points — a process that demands both precision and engineering insight.
Fuel tank panels across the wings were opened to facilitate internal visual and structural inspections, while all three landing gear assemblies were removed and exchanged with overhauled replacements. These tasks, which require a blend of technical mastery and OEM-specific knowledge, were conducted under strict procedural control.
Collaboration with Embraer Specialists Enhances Technical Rigor
Recognising the scope and international significance of the project, Embraer dispatched a dedicated team of specialists from its global support network to work alongside ExecuJet’s Australian technicians. These OEM engineers conducted critical bonding structure tests and provided remote support through Embraer’s contact centre, ensuring the inspection met the highest manufacturer standards. Their presence underscored the collaborative integration between OEM and MRO, creating a benchmark case for future heavy maintenance in the region.
ExecuJet’s General Manager for Melbourne, Rohan Coots, emphasised the strategic depth behind the selection: “We were chosen for this major check not only because of our experience but also our continuous support of this particular aircraft since its entry into service. Being an authorised Embraer service centre based in Australia was a critical factor.”
Workforce Development and Knowledge Transfer
To maximise the impact of this high-level inspection, ExecuJet drew in technical staff from its other Australian maintenance bases. This decision was part of a deliberate effort to foster workforce upskilling and promote internal knowledge transfer. Engineers and technicians gained hands-on experience with a complex airframe undergoing a full structural disassembly — exposure that’s rare even in experienced MRO facilities.
The 120-month inspection became a living classroom for best practices in handling the Legacy 500 platform. The insights gained here are expected to ripple through the company’s operations, elevating its technical proficiency across locations and laying groundwork for similar projects in the future.
Reinforcing Australia’s Strategic Role in MRO Services
This project is not just a testament to ExecuJet’s capabilities, but also a clear signal of Australia’s maturing aviation infrastructure. As high-performance business jets like the Legacy 500 become increasingly common in Asia-Pacific skies, the demand for complex MRO work close to home has grown. Rather than ferrying aircraft to distant maintenance hubs, owners can now trust local expertise supported by OEMs.
ExecuJet’s successful execution of the 120-month inspection positions Australia as a regional hub for Embraer support, complementing the OEM’s global service ecosystem. This evolution benefits operators across the South Pacific, New Zealand, Southeast Asia, and beyond — reducing downtime, logistics costs, and ensuring better lifecycle support.
Legacy 500: A Technological Marvel Meets Technical Excellence
The Embraer Legacy 500 is a super mid-size business jet, renowned for its blend of cutting-edge avionics, comfort, and performance. Featuring a full fly-by-wire control system, a six-foot flat-floor cabin, and a 3,125 nautical mile range, the aircraft demands a maintenance provider that can match its technological sophistication.
ExecuJet’s ability to meet this requirement reflects its evolution from a regional MRO to a globally recognised centre of excellence. The facility at Essendon Fields features OEM-approved tooling, climate-controlled hangars, and a suite of diagnostics and test systems built for modern aircraft like the Legacy 500.
The success of this inspection illustrates how legacy aircraft, when maintained by expert teams under OEM guidance, can continue to deliver peak performance well beyond their initial delivery years.
Client Confidence Rooted in Proven Relationships
For the customer — the original Australian buyer of the Legacy 500 — entrusting ExecuJet with such a critical inspection was a logical extension of a decade-long relationship. Since 2015, ExecuJet has handled the aircraft’s maintenance with unwavering consistency. This long-term partnership was key to anticipating and efficiently managing the vast logistics and technical intricacies of a 120-month inspection.
In such projects, trust is everything. The client’s confidence in ExecuJet’s meticulous planning, transparent reporting, and real-time coordination with Embraer ensured minimal disruption to the aircraft’s operational availability post-inspection.
Raising the Bar for Heavy Maintenance in the Southern Hemisphere
This successful project sets a new standard in the southern hemisphere for deep-level business jet maintenance. Heavy inspections like this — often routed to facilities in Europe or the United States — can now be performed closer to home, with no compromise in quality. For operators in Australasia, this opens a new realm of possibility in maintaining fleet availability and lowering total cost of ownership.
ExecuJet’s continued investment in tooling, training, and partnerships with OEMs like Embraer positions it as a future-proofed MRO entity. The company is no longer just a local provider — it’s a regional leader capable of executing complex inspections that meet or exceed international benchmarks.
Looking Forward: Opportunities for Growth in Advanced MRO
With this milestone now part of its track record, ExecuJet MRO Services Australia is expected to see increased demand from Embraer operators across Asia-Pacific. The successful Legacy 500 inspection adds credibility and confidence to its portfolio, which already includes multiple aircraft types and heavy maintenance categories.
The global business aviation market is steadily recovering, with increasing movements across corporate, charter, and private sectors. As fleet hours climb, the need for localised, advanced maintenance will become a strategic necessity, not just a convenience. ExecuJet, by building expertise in platform-specific heavy inspections, is ready to meet this demand head-on.
In a space where precision, reliability, and safety converge, ExecuJet MRO Services Australia has not only risen to the challenge but redefined what’s possible in regional aviation maintenance.
